Initially I tried to get the source of the URL and and extract the values which I was looking for the URL as given below
Dim URL = http://www.google.com
Dim oHTTP : Set oHTTP = CreateObject("MSXML2.ServerXMLHTTP.6.0")
oHTTP.setproxy 2,"<Proxy server:Port>"
oHTTP.Open "GET", URL, False
oHTTP.Send
And since the values which I am looking in the URL are proxy specific. And the values vary based the proxy server name which give explicitily as mentioned the above snippet.
I realised that giving proxy server name explicitlly is not the right approach since PAC file are used. Giving the proxy name only lists down the servers under that name.
So I thought opening a URL from browser such that it takes the PAC details in account and then draw out the neccessry values from there.
And opening a URL from the default browser is achieved as given below, I wanted to know is there a way extract the values from the browser.
CreateObject("WScript.Shell").Run("http://www.google.com")

I'm just dipping a toe in the water with Crystal at the moment and, as an exercise, trying to port one of my Python scripts across.
The script in question downloads the 'latest' PDF from a URL which takes the form: "http://somesite.com/download/latest/". When visited that URL automatically redirects to the page for the latest download eg. "http://somesite.com/download/4563/"
I'm having difficulty working out how to implement this in Crystal so that I can grab the actual URL that the redirect ends up on.
In Python I do:
currenturl = urllib.request.urlopen(latesturl)
#above will redirect to URL of format http://somesite.com/download/XXXXX/
#where XXXXX is the current d/load
endurl = currenturl.geturl()
...which gives me the end URL in the "endurl" variable.
But, reading the docs for Crystal's "http/client" I can't see any way to return the actual URL that a redirect ends up on. Is it possible?
Crystal's HTTP::Client currently can't automatically follow redirects.
Please note that you're reading an outdated version of the API docs, the current is at https://crystal-lang.org/api/latest/HTTP/Client.html (I don't think there have been relevant changes between 0.24.1 and 0.26.1 though).
But you can easily access the redirect URL from reading the Location header of an HTTP response:
response = HTTP::Client.get latesturl
endurl = response.headers["Location"]
I can't seem to get the embedded URL in a status, for example, in id=780804331608109057 -
https://twitter.com/i/web/status/780804331608109057
When I retrieve this via GET /statuses/:id, with include_entities set to true, the response looks like this:
"text":"Here\u2019s WSJ \"An Underwhelming Trump-Clinton Debate\u201d trying to spin this as something other than a Clinton triumph\u2026 https:\/\/t.co\/dpkmphGI8k",
"truncated":true,
"entities":
{"hashtags":[],"symbols":[],"user_mentions":[],"urls":
[{"url":"https:\/\/t.co\/dpkmphGI8k",
"expanded_url":"https:\/\/twitter.com\/i\/web\/status\/780804331608109057",
"display_url":"twitter.com\/i\/web\/status\/7\u2026","indices":[114,137]}]},
"source":"\u003ca href=\"https:\/\/about.twitter.com\/products\/tweetdeck\"rel=\"nofollow\"\u003eTweetDeck\u003c\/a\u003e",....
When viewed on my web client, the status instead displays the link to WSJ (referred through t.co) What I would like is one or both of these URLs to show up in my API response:
https://pbs.twimg.com/media/CtX5Sz8WIAAm4tq.jpg
what would be the short URL that looks like "t.co" followed by "/HJs4kbmTKz" (I have to break this up so SO doesn't complain.)
What am I doing wrong here?
The incredibly fast response from a staffer on the TwitterCommunity website was most gratifying:
You need to use tweet_mode=extended for the new longer Tweet format.
Ref: https://twittercommunity.com/t/missing-media-property-in-entities/70388/4
A search on this new parameter yields the appropriate documentation on dev.twitter.com - more documentation links on this mode probably exist out there. The most significant change appears to be that the key text is no longer used in non-compatibility mode - that's where the status text is, and unless you turn on compatibility mode, you have to now use the key full_text

I need to make sure that a URL that the user inputs goes where it should go. I mean if the user inputs "http://google.com/blablabla" or "http://google123.com/blablabla". I need to figure out that the second url is not correct because it won't open google's web-site. Is there some method in Swift to do that? Or do I just need to check if the URL contains "http://google.com"?
1. Malformed URL
To verify whether or not the URL itself is malformed, let the OS do it:
(check that the URL has all the parts it needs, namely a scheme and a host)
if let url = URL(string: rawStringInput),
let _ = url.scheme,
let _ = url.host {
// rawStringInput is well formed
}
You can then query all sorts of information from the URL, such as scheme (http), the host (google.com), the path (blablabla), fragment, port and so on.
2. Valid URL
If you want to know whether or not the URL is reachable (i.e. the remote server responds to it), you actually need to execute the request.
I use WCF and have a method like this:
[OperationContract]
[WebInvoke(Method = "GET", UriTemplate = "LoadProducts/{key}/{price}")]
XmlDocument LoadProducts(string key, string price= null);
price is string, inside LoadProducts I will try to parse it from string to double and do my other operations.
But in url, I can not get request any parameter for price like '24.25', '0.253' etc. It does not allow any value with dot.
localhost:13448/RestService.svc/LoadProducts/null/41.145
I get error "Please review the following URL and make sure that it is spelled correctly. "
How can I solve this?
Dots already have a meaning in a URL, they separate the target hostname, IP address or in the path they separate the resources from its extension. You will need to URL encode your request URL.
In .NET there is a method called UrlEncode to help you encode URLs. It is:
string url = "http://localhost/MyService/MyKey/24.25";
string encodedUrl = HttpUtility.UrlEncode(url);
Check out the MSN documentation for UrlEncode for more details.
I solved my issue. I switched server from Visual Studio Development Server to Local IIS Web Server, url took dot symbol inside parameter.
I am trying to get the right redirection URL for my sharepoint documents which then I can use to open documents in WebView of iOS. Currently I am giving the absolute URL for the document where the doc is rendered inside WebView as PDF(Image/Readonly). Whereas I want to redirect to office webapp. Now my issue is I dont know if the URL for office web app is something which I can construct like appending /_layouts/15/WopiFrame.aspx?sourcedoc= or is the URL custom based on installations and we need to call some Sharepoint API which will let us know what is the base URL for Wopi service.
Currently I am passing URL like - https://.sharepoint.com/Shared%20Documents/demo/demo.docx
Whereas I want to pass URL like - https://.sharepoint.com/_layouts/15/WopiFrame.aspx?sourcedoc=/Shared%20Documents/demo/demo.docx
Looking forward for help.
Thanks in advance,
Vishwesh
File f = clientContext.Web.GetFileByServerRelativeUrl("/sites/ /Shared%20Documents/Title.docx");
clientContext.Load(f);
clientContext.ExecuteQuery();
ClientResult<String> result = f.ListItemAllFields.GetWOPIFrameUrl(SPWOPIFrameAction.Edit);
clientContext.Load(f.ListItemAllFields);
clientContext.ExecuteQuery();
result.Value contains a URL, something like this:
http://sharep.xxx:8080/sites/zxxx/_layouts/15/WopiFrame.aspx?sourcedoc=%2Fsites%2Fzxxx%2FShared%20Documents%2FTitle%2Edocx&action=edit
Also you can extract the extract Office Web Apps URL from the above page, if you don't want to hit the sharepoint at all.
using Microsoft.SharePoint.Client;
using Microsoft.SharePoint.Client.Utilities;
// Assume we have these variables:
// ctx: A valid client context
// serverRelativeUrl: the URL of the document
File f = ctx.Web.GetFileByServerRelativeUrl (serverRelativeUrl);
result = f.ListItemAllFields.GetWOPIFrameUrl(SPWOPIFrameAction.Edit);
ctx.Load(f.ListItemAllFields);
ctx.ExecuteQuery();
This builds on the answer from #thebitlic which was the silver bullet for sure! However he or she is doing two calls to the server. Through the wonders of CSOM batching, it's possible to do it in one round trip, and no need to bring back the File object at all.
